Why Wall Preparation Makes All the Difference
No matter how premium your paint is, it will fail prematurely on a poorly prepared surface. Cracks, stains, and uneven areas prevent proper adhesion and create an unsightly finish — an issue compounded by the Mediterranean humidity of the French Riviera, which accelerates peeling and mould growth.
Professional painters in Nice typically devote up to 70% of a project's total time to preparation. Skipping or rushing this stage is the single most common reason homeowners end up repainting within just a year or two.
Surface Inspection and Cleaning
Start with a thorough inspection of every wall: look for cracks, damp patches, mould, flaking paint, and loose plaster. In older properties throughout Nice — from the Old Town to Cimiez — moisture infiltration is common and must be treated with an antifungal solution before any other work begins.
Remove all loose or peeling material using a scraper, heat gun, or chemical stripper. The surface must be completely dry, clean, and free of grease before you proceed to the next stage.
Filling and Levelling Imperfections
Fill all cracks, holes, and surface irregularities with an appropriate filler — a coarse base filler for larger defects and a fine finishing compound for a truly smooth result. Given the coastal climate of Nice, always opt for moisture-resistant products to prevent future problems.
Once each layer is fully dry, sand it down with fine-grit sandpaper or an electric sander. This step is essential for maximising paint adhesion and achieving the kind of perfectly smooth finish that professional painters deliver.
Applying a Primer
Primer is a non-negotiable step that too many DIY painters overlook. It bonds with the surface, improves paint adhesion, reduces the amount of topcoat needed, and prevents stains from bleeding through. For concrete or plastered walls, a deep-penetrating acrylic primer is the most effective choice.
Apply the primer evenly with a roller or brush and allow it to dry fully — usually 2 to 4 hours, though Nice's summer heat can speed this up. Resist the temptation to rush; applying paint over a still-wet primer will compromise the entire finish.
Final Check and Finding a Professional in Nice
Before painting, do one last inspection using a raking light held close to the wall — this reveals any remaining imperfections that flat lighting would miss. Mask skirting boards, switches, and window frames with painter's tape, and protect floors with a dust sheet.
